Reply To: Head and cylinder temps on 58 Johnson Super Seahoese 35

[Marcus]

Running engine in a barrel with water about 6″ above water intake, it was around 100 degrees out that day and water in barrel was quite warm to start with. the water spitting out of water /exhaust port is pretty hot. Ran engine before doing impeller for a few minutes and was pumping water, did not monitor temp at that time, I was so excited that it was running, but it had been sitting on a rotten boat for years so just figured it was time to change impeller. Bought parts from Sea Way Marine in Lynnwood Wa. Impeller is either OMC or Sierra. as that is what everyone. seems to stock. the thermostat seems to be working, after about a minute or 2 of running it starts a nice spray from exhaust/water port. Will try to get on lake and pump some nice cool water through and check temps. Was very careful to make sure that both water tubes were seated properly in new. pump grommets. Thanks to everyone out there for the help. I’m pretty new to this outboard stuff but I’m learning.
